Command Example (命令范例)

killall

  Send kill signal to all instances of a process by name (must be exact name).
  All signals except SIGKILL and SIGSTOP can be intercepted by the process, allowing a clean exit.

  - Terminate a process using the default SIGTERM (terminate) signal:
    killall process_name

  - List available signal names (to be used without the 'SIG' prefix):
    killall --list

  - Interactively ask for confirmation before termination:
    killall -i process_name

  - Terminate a process using the SIGINT (interrupt) signal, which is the same signal sent by pressing Ctrl + C:
    killall -INT process_name

  - Force kill a process:
    killall -KILL process_name
